Patrolling off the Irish coast, 20 miles south of Mine Head, at 1:30 p. m. the _Cassin_ sighted a submarine, but it vanished before the destroyer could get close to it. Half an hour later Commander Vernou sighted a torpedo running at high speed toward the ship. Double emergency full speed was rung, the rudder put hard left, and for a moment it looked as if the torpedo might pass astern. When only fifteen or twenty feet away, it porpoised, leaving the water and sheering to the left; and struck the vessel well aft, on the port side. When the torpedo was sighted, Ingram, who was at his gun, realized that if it struck among the depth-bombs astern, the explosion might sink the ship. Instantly, he ran aft to strip these charges and throw them overboard. He was blown to pieces when the torpedo struck. The memory of this heroic gunner's mate, who made the supreme sacrifice to save his shipmates, is preserved in the name of one of our new destroyers, the _Ingram_, the first naval vessel ever named for an enlisted man. There is no rank in sacrifice or honors. The officers and men worked heroically to save the _Cassin_. Her rudder gone, she was moving in circles. Efforts were made to steer by use of the engines, but something carried away and put the starboard engine out of commission. The ship seemed absolutely unmanageable. All was dark below, the electric generator having been disabled. Radio apparatus broken, a temporary auxiliary antenna had to be rigged up before assistance could be summoned by wireless. But the crew were undismayed, the gunners were at their stations, and when, at 2:30 o'clock, a conning tower was sighted, the _Cassin_ opened fire. Two shots struck close to the U-boat, which submerged and did not again attempt to attack the crippled ship. Just before 4 o'clock the _U. S. S. Porter_ arrived. At 9 the British ships _Jessamine_ and _Tamarisk_ appeared on the scene. But the sea was rough, the wind high, and it was not until 2:30 a. m. that a hawser was made fast and the _Tamarisk_ started towing the _Cassin_. An hour later the hawser parted. The _Tamarisk_, two trawlers and a tug worked until morning, attempting to get the vessel in tow again. But it was not until 10:37 a. m. that a towing line from the _Snowdrop_ was made fast, and the _Cassin_ taken to port.
